This adds a clang-tidy checker that can transform C++11-style type traits into C++17-style
variable templates. Variable templates can compile faster because they can be implemented
without instantiating classes.

I'm not very familiar with clang matchers; There's probably a better way to do what I
want than regex + hacky type checking, so suggestions are very welcome.
